How to provide a disk with read and write access using powercli command?

[LucD]

Do you mean a vDisk to a VM ?

Isn't that always RW, or what exactly do you mean ?

[PowercliCommuni]

Its a provisioning privilege.The action is to allow disk access.The description of that action is

Open a disk on a virtual machine for random read and write access.used mostly for remote disk mounting.

To add the disk you can use

$myvm=get-vm 'MyVmToWhichIwantToaddDisk'

new-harddisk -vm $myvm -capacityGB 10 -StorageFormat Thick

or

new-harddisk -vm $myvm -capacityGB 10-ThinProvisioned

if you need think provisioned disk

the rest it's about permissions, if you are administrator  and have administrator role then it should be fine. Now the question is do you need help with giving permissions via powercli or just adding the disk to vm

[PowercliCommuni]

Yes.I need help with giving permissions via powercli.Adding the disk to vm is working fine.

Can you tell exact privilege name ? Like when you are in vsphere client and you open the role settings, which one is it, not the description by in which section is this privilege and what name does it have, also please say which version on virtual center do you use

[LucD]

You will first have to create a role that has the required privilege.

Can you use any of the existing roles in vCenter or do you need to create a new role ?

For both you will at least need an account with administrator authority on vCenter.

privilege : Allow disk access

vCenter Version : 2.5

[PowercliCommuni]

I have to create a new role.Readonly role is there.how to give a disk permission with read and write?

[Grzesiekk · Accepted solution]

You need to create a role with this privilege:

Id              : VirtualMachine.Provisioning.DiskRandomAccess

new-virole

then you need to create new permission using this role that has this privilege in it

$privs=Get-VIPrivilege -id VirtualMachine.Provisioning.DiskRandomAccess

New-VIRole -Name My_New_role -Privilege $privs

for example... but this is just to show how can you build new role with this particular priv

[PowercliCommuni]

okay.I understood.Thanks for your help

[PowercliCommuni]

for get-viprivilege there is no argument like -id.Can we use -Name instead?

[LucD]

There is an Id parameter. Do a

Get-Help Get-VIPrivilege -Parameter id

Or have a look at the the Get-ViPrivilege cmdlet online reference.

[PowercliCommuni]

Yes.I got it.I had seen an older version powercli before.Thanks

[LucD]

Which PowerCLI version are you using ?

Do a

Get-PowerCLIVersion

The latest is 5.1, you should use that version.

[PowercliCommuni]

I had seen the documentation of powercli version 4.1.Actually i dont have the setup of powercli.
